Dodecahedron, Pedagogically Stretched

3D model description

####Dodecahedron Model, Pedagogically Stretched

D is for Dodecahedron

The present design allows students to make their own dodecahedron models and then play around and within it for mathematical insight such as the embedded cubes.

To play with the mathematical ideas, one needs a long elastic cord such as those for name badges (with some hard end covers), 20 vertices, and 30 edges. The inner edges of the connectors are trimmed for easy assembly.

###Among the Files

  1. Edges that come in various lengths, which cannot be mixed up, of course.
  2. Two versions of the vertex.

To assemble a dodecahedron, feel free to press the vertices against some hard surface or use a pair of pliers. Once assembled, it may be hard to take things apart. If so desired, please use the loose vertex or increase the printing resolution.
